I created a cloud for my company using Hyper-V (2008 R2...we chose M$oft due to crazy discounted prices because we're a non-profit and VMWare was much higher when we initially quoted). Worked fine for months. The Hyper-V and Failover Clustering showed the cloud was functioning fine, so I wasn't worried about that, but the SCVMM software that I really only use for P2V'ing machines started throwing Warning (13926) "Host Not Reponding" errors on my 2nd and 3rd (out of 3) hosts about six weeks ago. Not a big deal I thought, since Hyper-V and Failover Clustering showed fine and that's the main piece, but what I quickly found out was that SCVMM wouldn't let me P2V any longer. I went through the freaking GAMOUT in trying to fix this issue! Went through all Spiceworks posts I could find, pulled in my network guy to see if something wasn't configured right on the switches, NIC's or that domain, decided to venture in the crappy world of TechNet articles and did everything I could find on there, praying it wouldn't destroy my servers/setup.

Nothing worked.

Was on the verge of calling Microsoft when I looked up at the top of my 40+ tabs open in Chrome and decided to take one last look through all my open tabs and make sure I didn't miss something. Remember, I've been working on this for weeks now, but pushed off all projects and dedicated the past two days full-time as I need to get the last few physical servers off and into our cloud so I can cross that project off my list. Everything kept pointing me back to the following checklist for this particular error, on I kid you not, 20+ links I was reading via my umpteenth Google search: http://support.microsoft.com/kb/976640 . I double and triple-checked my work to see if I missed something, or if I incorrectly changed a registry setting, etc, but nope...did it all correctly, and still had the warning smacking me in the face.

Back to closing tabs.

Everything pointed to that one freaking "magical" link until I came across this one. Yup, a TechNet article...hate them...usually...but no longer...okay still a little. I quickly perused it and just as I was about to close the tab, I thought about something I saw...step freaking one said to check the login credentials. Normally step 1 or 2 in every Admin's checklist, but was overlooked due to just being overwhelmed with work lately. I totally forgot that about a month and two weeks earlier we changed the password to the account that SCVMM uses, but the reinstall I had just done for SCVMM went through without any issues, so that couldn't be it? Well for some reason when in SCVMM, I was grasping at straws before the eventual Microsoft call and the Administration tab caught my eye more than usual this time. I clicked it and immediately the "Managed Computers" section opened instead of it's normal "Overview" section. Right away, I see all my hosts, and the two problem ones showing "Not Responding" as a status...mocking me. I get even more mad, but then I see an option on the right that says "Reassociate". I think to myself, "Nah, couldn't be that easy." Link clinked...up pops a prompt asking for credentials, which I put in and are thusly accepted.

I again think that it couldn't be just that. I run a refresh on the cluster and VIOLA...stupid thing works now! I want to scream from the top of my lungs in victory to have gotten this dumb thing crossed off my list, but am even more frustrated that either I didn't see that step elsewhere when reading, or M$oft is too stupid to not put it as a first step?! CHECK YOUR LOGIN INFORMATION! /smacksself

Just had to share. Hope you all can laugh at my pain, roll your eyes, or maybe even fix your same issue through my headache!

An employee was using software that normally generates reports. Usually the program asks what program he'd like to open to report in, so he chooses Notepad. However, this "report" was an executable file, and Windows prompted the user to change the default program to open .exe extensions.

We are an SMB with a lot of in-house-developed applications in Visual Basic. One of our programmers is leaving on short notice. I'm the network guy and I have little experience coding, but I would like to learn so I can understand and modify code as needed.
